To all whom/,vizi Magnan/067%: V

Be it known that 1,* MARY EMM, a citizen of the United States of America, and a resident ofthe borough o f Manhattan, New YorkV city, and Stateof New York, have'invented certain n'ew'and useful Improvements in Storage Batteries, of which the following is a specitication.

My invention relates to electrical storage batteries, the positive and negative electrodes being put down in the ground andthe earth between the electrodes belonging to each cell moistened by a suitable chemical preparation, as hereinafter described, reference being made tothe accompanying drawing,which represents a vertical section of a series of cells constructed according to my invention.

a represents the positive electrodes; b, the negative electrodes; c, the earth in which they are placed; d and e, the terminal wires, and f internal connecting-wires; but these latter may be used or not at will.

A desired number of cells can be put down at suitable distances apart in a piece of ground of suitable area to avoid the action of the earth as one continuous electrolyte between the end electrodes, the space between the electrodes of each cellfbeing small compared to that between each cell. The cells thus constructed have the advantage of dispensing with vessels and insulating arrangementsof fordin'ary storage batteries.V l Theyar'e charged and discharged in a way similar toother storage-battery cells. I

l.V A storage-battery cell consisting of electrodes of suitable material, (for instance, lead electrodes prepared with peroxid of lead) put down in ground or earth of any kind, and a solution of suitable chemical material used as an electrolyte for exciting the electrodes.

2. A storage battery composed of cells consisting of suitable material, put down `in ground or earth of any kindand an electrolyte applied in any Way to the thus embedded cells, said cells placed at a distance apartk to neutralize the action of the 'earth as a continuous electrolyte.

3. A storage-battery cell consisting of one or more electrolytic substances of suitable chemical material applied to ground or earth of any kind, in Which electrodes of. suitable MARY EMME.
